The invention discloses the novel combined coenzyme Q10 parenteral solution, mainly containing the coenzyme Q10 as active component, polyethylene glycol 15-hydroxyl stearate as solubilizing agent and water for injection as solvent. One or more solvents of cosolvent, acidity regulator, osmoregulator and stabilizing agents can be also added. Low hemolyzation, extreme low histamine release and higher physiological tolerance of a novel solubilizing agent Solutol HS 15 adopted by the parenteral solution remarkably improves clinical medication security and the compliance of a patient; and the parenteral solution has the advantages of good stability, longer period of validity, higher medication convenience for a clinician, better storage and stable transportation, higher security for the clinical medication and better compliance of the patient. The parenteral solution also has the advantages of simple preparation technology, simple and convenient quality control and lower production cost, thereby being beneficial to industrialization production.
